Summary
A rare anatomic variation was found in a cadaver dissection: the superior thyroid and lingual arteries originated from a common thyrolingual trunk. This anatomical anomaly occurred on the right side of a 68-year-old woman.
Area of Science:
- Anatomy
- Vascular Anatomy
Background:
- Anatomical variations in cervical arteries can impact surgical procedures.
- Understanding normal and variant vascular anatomy is crucial for safe surgical interventions.
Observation:
- A cadaver dissection revealed an unusual origin of the superior thyroid artery and lingual artery.
- Both arteries arose from a common trunk, termed the thyrolingual trunk, on the right side.
Findings:
- The thyrolingual trunk originated 30 mm below the carotid bifurcation.
- The common trunk coursed 5.2 mm before bifurcating into the superior thyroid and lingual arteries.
- The arteries followed atypical pathways to their respective target organs.
Implications:
- Awareness of this thyrolingual trunk anomaly is essential for surgeons performing neck procedures.
- This variation highlights the importance of detailed anatomical knowledge in head and neck surgery.
- Variations in the origin and course of the superior thyroid and lingual arteries can affect surgical planning and execution.
